    Wow they are tiny!

    Not sure about the quality though, to me they look like they are made of cheap Chinese plastic...

    Yes they are tiny, they are 1:22 scale models :D

    The real rover weights over 100kg and is about 1.5 metres tall. The total landing mass including lander is greater than that of a 2014 Toyota Corolla

    compare to the apollos in the 70s this indeed is miniscule. have to wish them luck given the aspiration
    to set up bases on the moon. its better trying than not doin anything. an leap for mankind:-) ?

    The lander has a plutonium-powered nuclear generator. So why does it have solar panels?

    The Chinese are certainly making giant leaps(pardon pun) considering they are relatively new to the whole Space race.

    Its to keep it warm at night. Much smaller than an rtg.

    That explains the plutonium-powered nuclear generator. But why also have solar panels? If its got a nuke, surely it would have made sense to make it big enough to power all systems and save weight & fuel getting it there.

    They use a pellet of plutonium to provide heat. Theres no other machinery to allow it to make heat. It just radiates heat sitting there. No moving parts no nothing. So its a very lightweight heating solution. Turning that into an rtg requires a good few more parts, not to mention more plutonium to get the required heat output to deliver the required wattage.
    Hence the solar panels as they are very light by comparison.
    But i agree that an rtg would have allowed the rover to keep truckin 24/7. Costs i suppose?

    The lander, which does not move after touchdown, carries a plutonium-powered nuclear generator to provide electricity during the two-week lunar night.

    Thanks, I guess I shouldn't believe everything I read on the internet. I thought if it produced enough electricty to keep it warm at night, it wouldnt be too difficult to power a few instruments.

    Such a shame this isn't getting more attention. The first soft lunar landing in nearly 40 years!! This is huge. If it was an American mission no doubt the media would be all over it. Anyway best of luck YuTu! Looking forward to seeing lunar surface images.

    china needs resources. rare metals for our day to day electronics. probably running short on earth and now thinking of further afield. commerce drives space exploration. who decides who owns what on the moon? in the old days whoever got a flag there first was the owner. so america owns the moon?:D

    i wonder will the chinese rover "accidentally" knock the american flag(s) over:pac:
